A method and apparatus whereby information appearing on a CRT screen (410) is separately displayed in braille, using a braille web (100) in a loop form and made partly or wholly from a shape memory resin. The information from a CRT screen (410) is input to the web (100) by a braille printer (300) at a temperature within a range below the glass transition temperature of the resin. After the information has been read by the user, the displayed web portion is heated above the glass transition temperature by a heating roller (200) so that the web recovers its original, non-braille shape. The web is conveyed by a driving roller (210) along with the heating roller (200) and a driven roller (220) in the directions indicated by arrows in FIG. 1 for repeated use.

The present invention provides a membrane structure for a liquid gas storage tank. The structure is characterized in that the bottom wall of the membrane comprises a number of elongated corrugated members arranged in a square-lattice pattern, and each member has a pair of spaced, parallel, longitudinally extending corrugations. Also, the members are assembled by joining one end of each corrugated member to substantially the mid-point of another corrugated member extending normal thereto, and each opening between the corrugated members is closed and made liquid tight by a thin plate. Preferably, each corrugated member is a sheet member of U-shaped cross-section, having a pair of vertical flanges of equal height, located between a pair of sheet members of L-shaped cross-section which are arranged back to back in spaced, parallel relationship, the top edges of respective adjacent vertical flanges of said L-shaped and said U-shaped members being continuously welded together.
